Trebling aerial modeling combined special-shaped combination firework

Abstract

The invention discloses a trebling aerial modeling combined special-shaped combination firework. The trebling aerial modeling combined special-shaped combination firework is formed by combining a plurality of vertical barrel rows, leftward barrel rows and rightward barrel rows. Each leftward barrel row and the corresponding rightward barrel row which are adjacently distributed in the front and back direction form a V-shaped combination, and each leftward barrel row and the corresponding rightward barrel row in the front and back direction clamp the vertical barrel row in the middle to form a W-shaped combination. Propellant powder of single barrels of each barrel row is connected through fire transmitting leads in series, and the fire transmitting leads among the barrel rows are connectedthrough a fire passing lead in series on the side faces of the barrel rows. The fire transmitting leads are connected with the fire passing lead through a connection mechanism. The connection mechanism comprises a fire transmitting lead taper sleeve, a fire passing lead sleeve and a delaying quantitative insert. By means of the trebling aerial modeling combined special-shaped combination firework,the combination of an upward aerial effect, a V-shaped aerial effect and a W-shaped aerial effect is achieved, and the showing means of the combined firework is created; and a great number of ignition harness connectors of the large combined firework are conveniently, rapidly, efficiently, reliably and accurately connected, and the precise control over the setting off rhythm of the firework is ensured.

Description

technical field [0001] The invention relates to a combined firework. Background technique [0002] According to the definitions of the national standards of the People's Republic of China GB10631-2004 "Safety and Quality of Fireworks and Firecrackers" and GB19593-2004 "Combined Fireworks of Fireworks and Firecrackers" and other normative documents, combined fireworks are fireworks products composed of multiple single tubes. A single barrel is called a shot. The single tube is filled with propellant and effect drug (also called effect piece), and the single tube generally refers to a rolled paper bobbin. In the prior art, the aerial modeling scheme of combined fireworks display is monotonously repeated, and innovation mostly lies in the different collocations of colors and effects, which is difficult to meet the market demand of constantly improving taste. Contents of the invention [0003] In order to solve the above-mentioned disadvantages, the technical problem to be s...
